The Pastebin API wrapper Node deserves. better-pastebin is the most fully-featured module available for connecting to pastebin.com, both to its API and directly to the site itself for accomplishing tasks that the API doesn't support. It uses cheerio, request, and xml2js.

npm install better-pastebin

var paste = require("better-pastebin");

paste.setDevKey("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx");
paste.login("username", "password", function(success, data) {
    if(!success) {
        console.log("Failed (" + data + ")");
        return false;
    }

    paste.create({
        contents: "test contents",
        name: "test paste",
        privacy: "1"
    }, function(success, data) {
        if(success) {
            //data contains the URL of the created paste
        } else {
            //data contains an Error object indicating why the creation failed
        }
    });
});

paste.setDevKey("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx");

This is necessary before performing any other API call. It's synchronous, so it doesn't require a callback. You can find your devkey on pastebin.com after signing in.

paste.login(username, password, function(success, data) {
    //data contains this session's userkey
});

Logs in to Pastebin. Any actions requiring a login should be placed within the callback.

paste.get(paste_id, function(success, data) {
    //data contains the contents of the paste 
});

Gets the contents of a paste. Either the ID or the URL of a paste can be supplied.

paste.create(options, function(success, data) {
    //data contains the URL of the created paste
});

Creates a new paste. You do not need to be logged in to do this, but you can only create global or unlisted pastes as a guest. options can either be the contents of the paste as a string, or an object containing one or more of the following keys:

• options.contents: The contents of the paste; this is the only mandatory property.
• options.anonymous (default: false): If true, the paste will be created as a guest even if logged in.
• options.expires (default: "N"): When the paste should expire.
• options.format (default: "text"): The syntax highlighting of the paste.
• options.privacy (default: "0"): The privacy of the paste.
• options.name (default: ""): The name of the paste.

paste.createFromFile(options, function(success, data) {
    //data contains the URL of the created paste
});

Creates a new paste from the contents of a file. This works the same way that paste.create does, except that options.path should be specified instead of options.contents, or options should be the path to the file you want to upload as a string. It also accepts an additional key, options.encoding:

• options.encoding (default: "utf8"): The encoding of the file.

paste.edit(paste_id, options, function(success, data) {
    //data contains the new contents of the paste
});

Updates a paste's contents. You must be logged in to do this, and you can only edit a paste that you created. Either the ID or the URL of a paste can be supplied. options can either be the new contents of the paste as a string, or an object containing one or more of the following keys:

• options.contents: The new contents of the paste.
• options.expires: When the paste should expire.
• options.format: The syntax highlighting of the paste.
• options.privacy: The privacy of the paste.
• options.name: The name of the paste.

If left unspecified, these default to the paste's existing options.

paste.list(limit, function(success, data) {
    //data contains an array of objects of information about each paste
});

Lists up to 1,000 of the logged-in user's created pastes. limit specifies how many pastes to return; it can be a number between 1 and 1,000, and defaults to 50. You must be logged in to do this.

paste.listTrending(function(success, data) {
    //data contains an array of objects of information about each paste
});

Lists currently trending pastes. The array of pastes is identical in structure to the one returned by paste.list.

paste.delete(paste_id, function(success, data) {
    //data contains the ID of the deleted paste
});

Deletes a paste. You must be logged in to do this, and you can only delete a paste that you created. Either the ID or the URL of a paste can be supplied.

paste.user(function(success, data) {
    //data contains an object of information about the logged-in user
});

Returns information about the logged-in user. You must be logged in to do this.

N = Never
10M = 10 Minutes
1H = 1 Hour
1D = 1 Day
1W = 1 Week
2W = 2 Weeks
1M = 1 Month

0 = Public
1 = Unlisted
2 = Private

Note that private pastes can only be created if you are signed in. These values should be passed as a string, because 0 is a falsy value and can cause some issues.
